针对一类bang-bang类型连续微分对策制导律,研究了在离散信息模式下的数字执行方法.基于对线性系统和终端脱靶量性能指标的推导,提出一种bang-bang制导律常值最优离散化执行方法,可实现对于传统最优采样保持离散化方法的最好近似,同时可以避免抖振,更易于执行.针对3种连续时间微分对策制导律DGL/0,DGL/1和DGL/C进行了仿真.该方法也很容易扩展到其他bang-bang类型控制律的研究领域. Aiming at a bang-bang type of continuous differential game guidance law, the digital execution method in discrete information mode is studied.Based on the derivation of the linear system and terminal miss distance performance index, a bang-bang guidance law optimal value The discretization method can achieve the best approximation for the traditional discretization method and avoid the chattering and make it easier to implement.For the three kinds of DGL / 1, DGL / 1 and DGL / C simulation.The method can also be easily extended to other bang-bang types of control law research.
